To all whom t may con/cern,.-

Be itknown that I, JAMES K. PUTNAM, a

' `citizen of the United States, residing at Montpelier, in the county of Blackford and State of' Indiana, have invented certain new and useful Improvements in Rope-Sockets; and I do declare the following .to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains .to make and usethe same.

My invention relates to improvements 'in ropefsockets; and it consists in the novel construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

One-object of the invention is to provide a simple and efIicient device of this character by means of which rope or cable may be securely, but detachably, fastened to tools used in digging wells and the like.

A further object of the invention is to improve and simplify the construction and operation of devices of. this character, and thereby render the same more efficient and durable in use and less expensive to manufacture.

The above and other objects, which will appear as the nature ofthe invention 1s better understood, areaccomplished by means of the construction illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal sectional view through a rope-socket constructed in accordance .with my invention, showing the parts in clamped position ready for use. Fig. 2 is a view, partly in elevation and partly in section, of the body portion of the socket, showing the parts in disengaged position ready 10. for removal of the rope. Fig. 3 is a side elevation of the clamping members of the device, showing the same assembled. Figs. 4 and 5 are transverse sectional views through the same, taken, respectively, on the planes indicated by the lines 4 4 and 5 5 of Fig. 1. Fig. 6 is a perspective view of the casing or holder in which the rope and socket engaging jaws are mounted. Fig. 7 is a perspective view of one of the rope-engaging jaws. Fig. 8 isa perspective view of the bearing carrying the socket-engaging jaws. Fig. 9is a longitudi- ""`-bnal` sectional view through my improved socket, ixshowing a modified form f rope? clamping means which is especially adapted forsecuring a wire rope or cable in the soc llet. '-A Figs. 10 and 11 are transverse sectionaliviews taken, respectively, on the linesl 10 10 and 11 11 in Fig. 9. Fig. 12 isaperi ysp'ective view of the block orfholder for the socket-engaging jaws which is rigidly secured by the latter in the outer end of the socket shown in Fig. 9. Fig. 13 is a similar view of one of the socketengaging jaws shown in Figs. 9 and 11, and Fig. 14 is a similar view of one of the wire rope or cable engaging jaws shown in Figs. 9 and 10.

` Referring more particularly to Figs. 1 to 8, inclusive, of the drawings, the numeral 1 denotes the body of my improved'rope-socket, which, as shown, is of cylindrical form and has at one of its ends a screw-threaded socket 2, to receive the usual well-drilling tool or any other part or element, and at its opposite'end a cylindrical bore or socket 3, in which one end of a rope or cable 4 of any description is adapted to be detachably secured. A portion of the body 1 between its ends is reduced and formed with a polygonal face 5,

adapted to receive a wrench or similar tool to drilling-tool or other element screwed into the end 2. The socket proper, 3, has formed upon the inner face of its outer end radiallyarranged corrugations 6, which prevent the rope-clampingl members from being pulled out of the same. The inner end or bottom 7 of the socket 3 is preferably convex, as shown, and transverse openings 8 are formed in the wall of the socket in order to permit sand and sediment falling into the socket to discharge or drop out ofthe same, so that it will not become clogged.

When a hemp or manila ro e or cable 4 is to be secured in the socket 3,1; e parts shownA in Figs.. 6, 7, and 8 of the drawings are employed. These parts are a casing or holder 9, a series of rope-engaging jaws 10, and a series of socket-engaging jaws 11, which latter are united, as seen in Fig. 8. The holder 9 is in 'the form of a cylindrical tube, which has an outer diameter of sufficient size to permit it to be readily slipped into the socket 3 and an inner diameter slightly greater than that of the rope 4. This cylindrical holder 9 is formed with longitudinally-extending slots 12, whichare preferably three in number and which form longitudinally-extending arms 13, connected at their ends by integral rings grooves 16, which are disposed centrally with IOOl IIO

res ect to the slots or openings 12, and similar y arranged in the ring 15 or outer end of the holder 9 are transverse openings 17, as clearly shown in Fig. 6 of the drawings.

The slots or openings 12, of which there are preferably three, as shown, are adapted to receive the rope-engaging jaws 10. The latter have concave inner faces 18 to frictionally engage the ro e 4, and in their outer faces are formed two lJongitudinally-extending channels or recesses 19 20. The channel 20, which is of less width than the channel 19, is arranged centrall at the inner end ofJ the jaw 10 and extends om said end to about the center of the jaw, where it terminates the channel 19. The latter extends from the outer end of the jaw and lis of gradually-decreasing depth, so that wedge-surfaces 21 are formed. at the central and inner portions of the jaw upon each side of the small inner channel 20, as will be readily seen upon reference to Fig. 7. The socket-engaging jaws 11 have their outer faces corrugated, as at 22, to engage the corrugations 6 in the'outer end of the socket 3, and they are formed upon arms 24, which project longitudinally from an integral band or' rim 25. The jaws 11 are curved transversely and correspond in width Ato the width of the channels 1-9 in the jaws 10, in which latter they are adapted to seat and slide. Said jaws 11 are also tapered longitudinally, sothat they are wedge-shaped,

and their inclined inner faces 26 are adapted l to ride upon'the wedge-surfaces 21 upon the jaws 10. The^arms 24 are adapted to seat in the ooves or recesses 16 in the inner end of the older 9, and they are sufficiently resilient to permit the jaws 11 to be sprung over said end 14 of the holder when the arts are assembled as shown in Fig. 3 of t e drawings. At the outer ends Hof the jaws 11 are formed hook-shaped catches 27, which are adapted to spring into the transverse slots or seats 17 vformed in the outer end of the holder 9, as presently explained.

In assembling the parts as shown in Fig. 1 of the drawings the rope 4 is passed through the holder 9 from its outer end, and the jaws 10 are then seated in the slots 12 in said holder, so that the channels 20 will be at the l inner end of the latter and in alinement with 1, so that when the rope is drawn upon the holder 9, and hence the jaws 10, will be moved outwardly to a slight extent. This movement will cause the wedge-surfaces of the jaws 10 to coact with the Vwedge-surfaces 26 on the jaws 11 to cause the corrugations 22 in the latterl to firmly engage the corrugations 6 in the socket 3 and to cause the curved inner faces 18 of the jaws 10 to firmly clamp the rope betweenv them. When it is desired to detach the rope from the socket, the holder 9 is moved inwardly, so that the wedge-surfaces 21 and 26 ride downwardly ofi" of each otheruntil the catches 27 upon the jaws 11 spring out of the slots or seats 17 in the holder. When this takes place, the parts are released sufficiently to permit them to be removed from the socket 3, vand they will be retained in such position, as will be readily understood.

In the embodiment of my invention shown in Figs. 9 to 14, inclusive, of the drawings I employ a socket-body 1 similar to the one previously described and insert in the socket 3 in the latter two cylindrical blocks or bodies 31, by means of which a wire rope or cable 32 may be securely fastened in said socket. The outermost block 30 is formed with a longitudinally-extending bore 33, through which'theA wire rope 32 is adapted to slide, and in its outer face are formed longitudinally-extending dovetail channels or grooves 34, which are of gradually-decreasing depth from the outer end of said block to a point adjacent to ,its inner end. These dovetailed grooves or seats 34 receive and retain dovetail socket-engaging jaws 35, which are wedge-shaped longitudinally and have their outer faces corrugated, as at 36a, to engage the corrugation 6 in the socket 3. The block 30 is of slightly less diameter than that of the socket 3, and the jaws 35 are of such size that when they are disposed inthe outer portions of the grooves or seats 34 their corrugations 35 lie beneath the outer surface of the body. In order to retain the jaws 35 in this position for a purpose presently explained, I provide in recesses 36 in said grooves or seats 34 spring-projected studs 37, which are adapted to enter seats or recesses 38, formed in the inner sides of the jaws 35, as shown. In order to permit the latch-studs 37 to be disengaged from their seats 38, so as to release the jaws 35, I form in the latter in alinement with said seats 38 apertures 39, in which a nail or other pointed instrument may be inserted to depress said latch-studs, as will be readily understood. The inner block 31 is also of cylindrical'form and is formed with a longitudinally-extending bore or opening 39a, which is wedge shape, as shown, to receive two simi-v lar-shaped rope-engaging jaws 40, the inner faces of which are concaved and corrugated or roughened to cause them to firmly clamp the inner end of the wire rope 32. I preferably employ a cushion 41 between the opposing ends of the blocks 31 32. This cushion may be of any suitable kind. For the IOO IIO

purpose of this speciiicationit is here shown as a coiled spring. In assembling the parts of this embodiment of the invention'the end of the wire rope 32 after being passed through the bore 33 ofthe block 30 and the coiled spring 41 is secured' in the block 31 between the two wedge-shaped jaws 40.

The block 31 is then inserted in the socket 3 and the block dropped into the outer pori firmly engage the corrugations 6 in the socket l3. The block 31 will thus be retained in i connected to the socket-body 1.

he socket 3, and the spring 41 will serve 'as a cushion between the rope and the tool When it is desired to disconnect the rope 32 from 'the socket-body, the block 31 is moved inwardly,

so that the jaws 35 ride downwardly into the deep outer portions of the seats 34 until the latch-studs 37 spring into the seatsor recesses 38 in said jaws 35, so that the latter will be held in theirretracted positions and the block 30 may bereadily removed from the socket.

From' the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advan.

tages of the invention will be readily understood without requiring a more extended eX- planation.l

Various changes in the form, proportion, and the minor details of construction may be resorted to within the scope of the appended claims without departing from the principle or sacrificing any of the advantages of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Lotters Patent, is-

1. The combination of a body having a socket formed therein with corrugations in its outer portion, a holder slidably mounted in said socket, a socket-en aging jaw carried by said holder to force sai jaw into engagement with the corrugations of said socket, and means for retaining a rope or the like in said holder.
